Underpaid rents

[Roy Sloan]

I have a five bedroom property rented to college student in New Jersey. The lease has all five tenants names on it. One tenant moved out without notice and the remaining tenants don’t want to pay the whole rent, just 4/5 ths as they feel I should be going after the 5th tenant for the balance. My options are to enforce the lease and evict, sue and try to recover the money owed me or renegotiate and bite the bullet until next May taking a $3000 loss. Any advice from New Jersey landlords would be greatly appreciated.
